Problems solved by technology

However, since in the AG coating method, sharpness of a screen is deteriorated due to surface unevenness, recently, the AR coating method has been variously studied.
However, in the method of forming a plurality of layers as described above, since a process of forming each of the layers is separately performed, close interlayer adhesion (interfacial adhesion) may be weak, such that scratch resistance may be deteriorated.
However, in the case of using the particles with a nanometer size, it was difficult to increase scratch res...

Preparation Example: Manufacturing of Hard Coating Film

[0177]A salt-type antistatic hard coating solution (KYOEISHA Chemical Co., Ltd., solid content: 50 wt %, product name: LJD-1000) was coated on a triacetyl cellulose film using a #10 Mayer bar, dried at 90□ for 1 minute, and irradiated with UV light (150 mJ / cm2), thereby manufacturing a hard coating film having a thickness of about 5 μm.
